Mozilla sandboxes [1] its subprocesses in very baroque and fanciful ways (not
saying it shouldn't -- rather musing we shouldn't be here at all).

The sandbox keeps subprocesses from "seeing" things in the file system [2],
thus also unable to load shared objects. But ISTR that audio subprocesses
are allowed more as of late (i only half-know those things from banging my
head against apulse: take with two grains of salt).

That said, I thin Max's observation elsewhere in this thread is far more
relevant than mine. Some (perhaps non-free) codec might be missing.
